I highly don't recommend this update. If this version firmware of MEI isn't in BIOS, it is due to some reasons.
If your PC appears stable, it doesn't mean that is really stable or compatible with your board or BIOS.
Don't worry the Intel ME is compatible with the board, is functioning correctly its more stable even with higher memory frequency.
What happened is Intel boxed us out on knowingly but it's as easy as updating the ME, what i don't recommend is going above 9.0 xxx to 9.1 xxx version read the website it has all useful info
Plus I'm not employed by Intel but i would gladly take a job from Intel and revive the desktop board department for Intel
I too do not recommend that folks do this!!!
The BIOS has no support for this processor. What this means is:
- If any special initialization is required by the processor, the BIOS is not performing it.
- Every processor has errata (read: bugs) in its microcode. One of the things that the BIOS does during initialization is load a microcode update that provides fixes for all known errata. Because this board's BIOS does not have support this processor, it has no microcode updates to install for it. Net result, these errata are present and operations that the processor is performing could fail randomly.
It is only a matter of time before one of these errata hits you, potentially with catastrophic results. You are lucky to have gotten as far as you have. You could see a failure at any time.
Thank yo and thank you all for this info, but i highly doubt it, been one week now still going strong in fact I've been running all tasks i used to run ad all is well several stress tests here and there and still works and is stable, using memory i couldn't push to 2133 or 2400 with the previous me and CPU running stable at 2133 1.5V
So i hope nothing bad happens and i have a feeling it wont happen, Intel just better admit and release a BIOS with official support for all though for me I'm fine and ok as mine works accordingly.
Followed instructions and WOW, no more manual power cycle during reboots--thank you "stephenb.b.r"
This is a really neat thread! I've studied coreboot (an alternative BIOS) a bit which sort of leads me to believe that this solution is actually perfectly acceptable. CPU microcodes, while in the BIOS, are often applied later during the OS boot process, for instance, Windows recieves Intel microcode updates, so in terms of errata, your OS ought to cover that. When looking at coreboot for Intel processors there are two very crucial bits of code you need to get the processor going: Intel ME and the Memory Reference Code. I believe the memory initialization code is chipset dependent--seeing as the chipset is the physical hardware on the motherboard, this code probably doesn't need modification So, from a sort of high-level view of BIOS, this seems very satisifactory in terms of compatbility.
CONFIRMED! Appreciated...so cool!!!! And a bit uncool from Intel to act in this fashion.
My story (brief): A SUCCESS
- Intel DZ87KLT-75K - unknown BIOS from production upgrade from previous Intel C2Q Q6600 on a Win 8.1 64bit install
- Not starting at all with i5 4690 Haswell Refresh
- Flashed with a borrowed Celeron G1849 to 0457 BIOS (latest to date) via F2 => F7 method through BIOS
- The so called "incompatible" processor runs/boots etc.. Some issues: yes, as described.
- Power issues (no shut down, restart etc.) were present.Could be usable with it, however.
- This BIOS has IME FW version 9.020.xxxx
- *you missed to mention only that BEFORE using the Intel ME flasher you need to install latest IME drivers Downloads for Intel® Desktop Board DZ87KLT-75K for Windows to be able to operate with all Flasher tools linked. (otherwise Info tool and Flasher give errors and will not operate).
- Everything else run as described. Flash under Command prompt with the Win64 tools. (suggest you copy the FW file in one dir for full convenience) Total like 15 mis of work if you do it first time with all checks that can be spared.
=> Bottom line: JUST WORKS PERFECT (so far) all power management issues seem to be in control. Windows shuts down/restarts autonomously.
So this thread got me to actually try this out with a different board. I can verify that this procedure also works with a DQ87PG board using an i7-4970S processor. I suspect it would work with any 8-series board really.
As a side note, the DQ87PG needs the 5Mb ME firmware to operate. I am not sure I was really having issues before upgrading the ME--didn't really test that. But the moral of the story is that the larger ME firmware for Q87 chipsets and such also seems to work just fine!
I just wanted to say that this also worked for me using a DZ87KLT-75K + 4790K. You are the man stephenb. Thanks for your efforts in sharing this with us. I love this board, and you probably just gave me another 1-2 years of use out of it.
Thank you all for the feedback and useful information that will help many users, I would gladly take the helm at Intel to head the New Desktop Board team if they ever want to get back in to the business
Thank you for sharing your comments.
Hi guys, this is a great post, I was really worried I wasn't going to be able to use my board with the 4790 I just bought. I had the DZ87KLT laying around from a build I did a few years ago but ended up using a different board. I decided to pick up a 4790 to use the board I already had but hadn't used. I had no idea that intel wasn't supporting their own processors and I probably would have gone with a new processor/board combo had I known. Anyway now I'm stuck with a brand new 4790 that won't boot. I'm guessing the bios on my board is just too old for it to work at all. Does anyone know if you can update the bios without a compatible processor installed? Using that recovery bios feature maybe? Or do I need to pull the 4770 out of my other build to do it? Also at the time of writing this intel's download site is down, can any of you send me the version of the bios you're using?
Any help would be hugely appreciated!!
